Dear Client,
I have read your project requirement and I will fix the Magento 2 category tree structure from the CSV file. I have completed so many projects of uploading products, categories, and data from the CSV file. I have made a special kind of extension for these types of jobs.
I have been working as a Magento developer since 2013. I have designed and developed around 50+ E-Commerce sites only in Magento.
I have got expertise in designing, development, integration, migration, setup-installation, synchronization, and any types of customization in Magento.
Let me know further details of the project.
Thanks,
